Abstract

Advances in semen quality analysis technology are developing rapidly. Computer-based semen analysis technology provides a more objective assessment of spermatozoa motility by measuring various kinematic movements of spermatozoa cells. This study aimed to analyze differences in spermatozoa movement patterns using Computer-Assisted Semen Analysis (CASA) in various goat breeds. This study used frozen semen from four goat breeds: Boer, Ettawa crossbred (PE), Saanen, and Anglo-Nubian. Parameter observations were conducted on thawed frozen semen from two straw samples for each group, consisting of six replicates from each breed. The observed sperm kinetic movement characteristics were VAP, VCL, VSL, DAP, DCL, DSL, STR, LIN, WOB, ALH, and BCF. The results showed that sperm movements did not differ significantly (P0.05) in VAP, VCL, VSL, DAP, DCL, and WOB. There were significant differences in DSL, the highest in Saanen 21.993.01 m/second, the highest STR and LIN values in Boer 0.690.04% and 0.450.03%, the longest ALH Anglo Nubian 6.190.39 m, and the largest BCF Boer 25.561.87 Hz. This study concludes that differences in goat breeds affect the kinematic movement of spermatozoa as measured by CASA in the parameters of DSL, STR, LIN, ALH, and BCF.

Abstract

Kolaka Regency is recognised not only as a major rice producer but also as an important centre for smallholder livestock farming. The Rice-Cattle Integration System (R-CIS) has been identified as an effective approach to optimize local agricultural resources for smallholder livestock development. However, its dissemination has remained limited due to the uneven carrying capacity of rice fields across different regions. This study aimed to analyse the current and projected carrying capacity of rice fields in Kolaka Regency, Southeast Sulawesi (20232024), considering land availability, livestock population, and feed resources. Data analysis included assessments of land carrying capacity, livestock density, livestock concentration index (LCI), and feed concentration index (FCI). Results indicated that Kolaka had 12,203 ha of rice fields, producing 3,188 tons of crude protein (CP) annually from unfermented rice straw and 10,539 tons CP/year from fermented straw. Feed distribution within the regency was uneven: in districts such as Baula, Pomalaa, Samaturu, Wolo, and Wundulako, livestock populations could be increased, whereas Toari and Watubangga exceeded carrying capacity even after straw fermentation. The study estimated that fermented straw could support an additional 24,335 livestock units (LU) across Kolaka Regency, equivalent to about 2,028 LU per district annually. These findings highlight the need for inter-district feed substitution and livestock redistribution. Overall, fermented rice straw significantly enhanced feed availability, thereby supporting sustainable livestock production.
